Hello! I agree, it looks like you're missing the old mounting bracket. The one you still have looks like our 39-513, so the opposite hand side that's missing would be the 39-514. I'm less certain about the screw. Some customers have used the 33-083 in the past to secure these, but that's no guarantee it will work for you. The length especially is in question. I recommend taking one of the old ones to a local hardware store to have them match up the size. |
